Application filed oca eraa, 19 25.

gates ofv the automatic type to be used are desir'able'or necessary and, as an' exampleof one of its many uses, the same hasfbeeno shown in'a diagrammatical way in connection with our store arrangement application, filed 'inthe United States Patent Ofiice on even date;

' showing the upper portion of the hollow post herewith.

It is the primary object of thepresent invention to provide an effective and simple automatically opening and closing the gate members eitherin connection I slug operated releasing mechan sm or entirely withoutthe samev as the case mayfre uire. M

A, further object provision of a novelly swinging the gate members to the open and closed positions without the use of expensive and complicated parts p An even further object o f'the invention is the contemplation of means for automatically opening and closing gate members which is housed within the spaced apart posts of the gate and which is operated by means of a depressible plat form between saidposts. p I I v A still further object of this invention is to clearly show the use of effective counting means for the gate which records the number of persons passing therethrough, as wellas to set forth a member engageable by any suitable coin or slug operated means which must be released before theplatform' can be depressed or the gates swung, to'the open position. I I

'Themany min orv objects of this invention, such as the specific wayof constructing the spirally twisted operating rod or'b'ar, will be fully set forth in the following specifi cation referring to the accompanying draw ing in which: s

Serial No. 65,610.

Fig. 3 is an enlarged fragmentary detail view of the cam surfaces or twisted portion,

of the operating bar.

"Fig/4i is a section'through the bearing which operatively joins the vertical rods and v rtical fragm y V-V of Fig. 1 and Fig. 5 is an enlarged section taken on line which holds the counting device" and any meansfor releasably locking the entire structure in the closed position'until a coin or suitable slug is inserted, and

'Fi x' 6 is a cross section of the same taken several views, the numeral 7' designates a' hollow post of which there are two, spaced apartas shown in Fig. 1 and adapted to rest upon or be fastened to the floor 8 'through their respective bases 9.

Each hollow post 'serves as a housing for the vertical swinging and support bar 10which passes longitudinally thereof from a point below the base '9 to within a short distance of the top of post 7. Bar 10 should be supported-for rotary and vertical reciproeating movement bybearings 12', rigidly carried 'by the walls of post 7, and a pair of suitable guide bearings 13 also'similarly' supportedto engage bar '10 adjacent the cam surfaces 14 formed by the spiral twists. Bar 10 is rectangular in cross section, and passes through rectangular openings 15 formed by each bearing 13; To form the out the function of, making a turn'of ninety degrees "when bar 10 is forced'through openings 15, the same should be twisted spirally as shown in Fig. 3. a

7 A gate member '16 is supported by each bar 10 and should be constructed to present an upper and a lower portion 17 and 18 respectively which are ofa size suitable to pass through the'slots 19 formed inthe side of each post 7 Slots 19 extend a, quarter way around the post 7 and angle downwardly to'allow free turning and lowering slightly of the gate member'16 when bar 10 is moved vertically. The gate member 16 swings open only when bar is pulled down. This is accomplished in an automatic manner by recessing floor 8 as shown in Fig. 2, joining the lower ends of each bar 10 by a link 2( and causing a depressible platform 21. to rest thereon after the platform has been hinged as at 22 to the floor 8 and along one of its sides. 1C i Any suitable bearing 23 such as the wellknown thrust bearing may be used to interconnect bars 10 and link 20 so that when link 20 is exerting a downward pressure, the same may rotate when cam surfaces 1 1 engage opening in bearing 13. Obviously, platform 21 is caused to exert the downward pressure on link when a person steps upon it preparatory to. entering the gate. When the platform 21 is depressed, the gate members are both in the open position as shown in dotted lines of Fig. 2. v g

It may be desirable. to include a counting mechanism 2 1 to record thenumber of persons passing through the gate. This mechanism may be of the ordinary type, supported by one of posts .7, ed to the gate member through a rod 25 which has a squared end adapted to fit into squared socket 26 of gate member 16. This construction permits the gate to raise and lower therequired distance during the turning, yet operate mechanism 24.

f required, any suitable mechanism for releasably locking the gate may be included in the complete assembly. Any means operated through the coin or slug 27 may be employed. For purpose of illustration, gate 16 is kept from turning by lever 28, pivotally mounted as at 29 and normally held behind lug 30 by a spring 31. \Vhen a coin 27 is passed in through slot 32 and against foot 33, the lever 28 is brought out of engagement with 111 30 long enough to permit the person standing on the platform 21 to pass through the gate. lVhen platform 21, bar 10, gate members 16 and lug 30 are again pulled back bY'COll spring or other suitable means 34., the gate is again ready to be resoperated and opened by the following perso To show the device in a compact and conipletely housed state, spring 3 1 has been illustrated as exerting constant upward pressureon link 20 by joining the same with one of the rigid bearings 13. This retrieving construction may be varied if desired.

7 Having thus described theinvention, and reserving the right to make all such modifications and changes as might fairly fall withinthe scope of the appended claims, what is claimed. and desired to secure by Letters Patent is:

1. In a gate of the character described a pair of spaced apart tubular posts, means correspond .to
